Pcb through hole clearance
SpletNormally, when calculating the PCB hole diameter, the aspect ratio between the diameter of the hole and the thickness of the board is considered. If the thickness is 1.60mm, the hole size should be about 0.40. This means that the aspect ratio, in this case, is 1:4. Reducing the thickness of your PCB means that this ratio should also be reduced. Splet19. apr. 2024 · In those locations, the components should be set back 0.125 inches from the tab, while taller parts should have a clearance of 0.250 inches. Physical support: Some circuit boards require additional support during manufacturing due to the overall size, thickness, and weight of their components.

Actually, the plated-through slot is the plated-through hole pads with non-circular shape. Circular plated-thorough holes are the ideal choice for most through-hole components. But there are many components …
Splet12. maj 2024 · I set this to 1.9mm because I want 7mm diameter clearance. The hole has a radius of 1.6mm (M3, 3.2mm hole). 7mm diameter clearance = 3.5mm radius. 3.5mm - 1.6mm = 1.9mm. This results in the following: This looks pretty much what I was looking for, i.e. a 3.2mm hole for a M3 screw and 7mm diameter clearance without any copper.
